Abstract: A szitalap (1) párhuzamos sorokban (2, 3, 4, 5)
hullám alakban egymáshoz csatlakozó kiemelkedésekkel (6,
6'; 9, 9') és bemélyedésekkel (7, 7'; 10, 10') rendelkezik,
amelyek között sorról sorra (2, 3, 4, 5) egy fél
szakasznyi (8) fáziseltolás van, úgyhogy olyan lyukak
(11) keletkeznek, amelyeket mindig egy kiemelkedés (6, 6';
9, 9') és egy bemélyedés (7, Ί'; 10, 10') határol. Mivel
az egyik sor (2) kiemelkedéseinek (6, 6') csúcsai a következő
sor (3) bemélyedéseinek (10, 10') aljába mennek
át, egy lépcsőzetes szitalap keletkezik, amelynek síkjához
képest a lyukak (11) ferde helyzetben vannak. A kiemelkedéseket
(6, 6'; 9, 9') és bemélyedéseket (7, 7'; 10,
10') olyan felületek határolják, amelyeket pl. körívekből
álló hullámvonalat vagy fél hat- vagy nyolcszögekből álló sokszögvonalat követő párhuzamos alkotók képeznek. A kiemelkedések
(6'') csúcsánál, a lyukak (11) felett lapos
felület (12) alakítható ki. A szitalapot úgy állítjuk elő,
hogy egy lemeztáblába a sorok szélei mentén fáziseltolással
réseket vágunk be, majd a rések széleire kifejtett ellentétes
irányú nyomással azokat szétnyitjuk.

Title: Method of making diamond compacts for drills
IPC: B01J3/06
Filed: 1980-10-13
Abstract: An improvement in the manufacture of diamond compacts is disclosed in which a cylindrical mass of polycrystalline diamond is surrounded by and bonded to an outer mass of metal which provides support for the diamond. The improvement comprises the use of seed diamond to grow the polycrystalline mass under high pressure-high temperature (HP/HT) conditions from non-diamond carbon, utilizing a catalyst metal contained in the outer metal annulus. Preferably, this improved process is carried out using a cup-shaped metal mass having a stable carbide content of at least 10% and a coefficient of thermal expansion slightly higher than diamond. It is also preferred to heat the sample (the outer metal mass and the inner graphite mass) directly by passing an electric current through the outer metal mass in the HP/HT process during which the polycrystalline compact is formed.

Title: Method and apparatus for applying a weld bead to a thin section of a substrate and an article of manufacture
IPC: B23K9/06
Filed: 1987-02-19
Abstract: The welding method is used to lay down weld beads on metallic substrates with a thin section, e.g., of down to 0.030 inch. The process employs a plasma transferred arc which is generated at low current, e.g., between 0.5 amps and 60 amps, and with a very high superimposed frequency, e.g., 15 kHz. A low amount of heat is generated so that the thin section is not burned through. The welding powder is delivered into the arc and becomes metallurgically bonded to the substrate.

Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To stabilize and improve the sucking performance of dust by controlling a drive motor so that the rotating speed of a wheel is lowered when the interior humidity is higher than a preset humidity. SOLUTION: A control body 52 for floor brush has a sensor for catching the interior humidity, and changes the rotating speed of a driver motor 40 according to the detection data to change the traveling speed of the wheel of a floor brush. Namely, when a power source switch 56 is ON to drive the electric blower 21 of a cleaner body, the driving fan of the floor brush rotates a rotary brush, and the dust on a floor surface is sucked by a suction port and sucked to the cleaner body through a connecting pipe. When the humidity in a cleaning room detected by the sensor is higher than a preset humidity, for example, 60%, the driver motor 40 is controlled by the control body 52 so as to reduce the traveling speed of the wheel of the floor brush regardless of the detection result of a dust detector 42. Consequently, humid heavy dust can be surely sucked.
